ant colonies for protection from predators, to find a place to sleep, and so they can get food easily without having to look too hard themselves.
Parker agrees, adding that the strategic use of
ants by
other species is an underexplored area of biology: «This is evolution at its most extreme: the more we look, the more these creatures force us to modify our ideas of how organisms make a living.»
Other species were also identified, like earthworms,
ants, termites, centipedes, beetles, grasshoppers, cockroaches and woodlice, which may also be called «ecosystem engineers» (specifically earthworms, termites and some
ants) because their activities modify the soil, enriching its productivity.
Many
other species independently evolved stunning strategies; for example the caterpillars of most Lycaenidae butterflies life obligatory in
